1 50 years young! The 21 st Century Mainframe

2 Agenda Introducing the 21st Century Mainframe Mainframe 101 New stuff Cool stuff Managing the 21st Century Mainframe Scheduling Automation Storage

3 Introducing the 21 st Century Mainframe Mainframe 101 New stuff Cool stuff NASA used mainframes Jets use IMS Desert Storm used a 4381 ATMs use CICS

4 Mainframe 101 Not JUST used in Finance! All use mainframes every single day!

5 Mainframe 101 z/auditing Essentials Volume 1 IBM first announced MVS as the operating system to run its big iron way back in April In the 49 years since, it has morphed into z/os running in increasingly complex configurations on System z with the very latest zenterprise hardware. The platform has bucked the Technological Discontinuity trend identified in the Stages Theory of Computer Growth, described in an early Harvard Review article. It has done this by continually evolving to serve Business better.... The System z environment is becoming increasingly complex (with five different GA operating systems available currently and more in the pipeline) and critical to Business (some 80% of the world s business data lives behind a mainframe). But there are some damaging myths that surround it at the moment.

6 Mainframe 101 Myth 1 They are old technology and nobody uses them anymore Truth 1 Sure the mainframe will be celebrating its 50 th birthday this year The car is even older technology but no one believes that a Model T Ford is the same beast as a Subaru Imprezza! Today s mainframe is exponentially faster, bigger and better than the 1964 version 96 of the world s top 100 banks, 23 of the 25 top US retailers, and 9 out of 10 of the world s largest insurance companies run System z 71% of global Fortune 500 companies are System z clients 9 of the top 10 global life and health insurance providers use System z Mainframes process roughly 30 billion business transactions per day including most major credit card transactions and stock trades, money transfers, manufacturing processes, and ERP systems

7 Mainframe 101 Myth 2 They only run legacy applications Truth 2 TCP/IP was rewritten in 1997 to allow out of the box communication Unix Systems Services (OMVS) around the same time CICS Transaction Gateway WebSphere Application Server Domino Java Linux on z since Web enablement leg a cy /ˈlegəsē/ Noun An amount of money or property left to someone in a will. Adjective Denoting software or hardware that has been superseded but is difficult to replace because of its wide use. Synonyms Heritage, bequest, inheritance, patrimony

8 Mainframe 101 Myth 3 They are really expensive Truth 3 Initial outlay *IS* more than a Windows server Total Cost of Ownership is another matter The mainframe delivers: higher utilization lower overheads lowest total cost-per-user of any platform

9 Mainframe 101 Myth 4 All the people who know how to run them are dead! Truth 4 Erm, do I really have to address that one? OK, I will! Yes, classic mainframe personnel ARE getting older but... IBM Academic Initiative University of Canberra GSE UK Conference 101 Sessions in all streams Students invited Our real legacy must be to make sure System z runs for another 50 years

10 New Stuff Linux on z Scalability reduce license fees Oracle... cough! and even reduced support cost from SUSE and RedHat (per IFL) reliability of the z platform

11 New Stuff Oracle Model Size of Config Number of IFL's Enterprise Linux Servers With Service Management setup x86 Cores non virtualised X86 Cores Virtualised Oracle Nonvirtualised Oracle virtualised Oracle on Linux for z z114 small 2 143, , ,000, ,000 50,000 medium 6 260, , ,000,000 1,200, ,000 large , , ,000,000 2,000, ,000 z196 expandable 6 448, , ,500,000 1,800, ,000 supersized 32 1,600,000 1,823, ,000,000 9,600, ,000 N.B All IBM Pricing is subject to Special Bid and is purely for indicative purposes N.B Oracle cost are assumed to be 25K per core

12 New Stuff Ziips & Zaaps ever increasing eligible workloads not just supporting tradition z applications but also XML and Java allowing the customer to offer Java Web apps with the level of reliability required when running business applications using mission critical data

13 New Stuff WebSphere 3rd party middleware MS Biztalk can speak with: COBOL apps WebSphere MQ z/os hosted files and DB2

14 Cool Stuff Airlines Ticketing systems Flight statistics etc Direct Line Rates tables stored in CSA All quotes access mainframe even those initiated on the internet JD Williams Marisota Jacamo Mark and Spencer Warehouse controls

15 Managing the 21 st Century Mainframe Scheduling Automation Security Storage Web Enablement

16 Scheduling 3 rd Most Important piece of enterprise software Responsible for ensuring critical business processes are carried out on time and in the correct order Everything from customer billing to employee payroll via daily to yearly reporting jobs For a large enterprise this can amount to 10,000 s of interlinked processes every day

17 Automation 2 nd Most Important piece of enterprise software Responsible for maintaining the computer environment and all of the resources used by all the other enterprise software Ensures all of the day to day system activities are carried out on time and in the correct order, every time. It doesn t take holidays, get tired or go on strike Any process that can be check-listed can be automated For large enterprises this can involve monitoring 1,000,000 s of events across multiple environments in a single day

18 Security Most Important piece of enterprise software! SAF RACF CA ACF2 CA Top Secret Most Securable Platform Over reliance on defaults and lack of applied knowledge can leave the platform as open to Hacker Attacks as any other

19 Storage Space Management Backup and Recovery Efficiency

20 Web Enablement FedEx Parcel Tracking Online banking zbx
